Convert UPD to FSLogix container

Roger Critz 

OK so here is what I have so far. It's actually functional and I think anyone can run it in their environment.

It will get the list of files for X:\Path\UVHD-<SID>.vhdx and then give you X:\Path\SAM_SID\Profile_SAM.vhdx

It takes about 11 seconds per VHDX file. There's a 5-second delay on the mount and dismount step just to make sure that process has completed before moving onto the next file.

There's one problem in my environment but it's not the code itself. About 1 in 20 source VHDX files fail to mount. e.g. Mount-Diskimage -ImagePath X:\Path\to\the\file.vhdx. The error is 0x80070005.

I've tried on multiple servers and accounts. It's not NTFS permissions or lack of admin rights. I haven't found the cause yet.

If you comment out the part where it does any actual changes and leave only the mount and dismount sections then you can see if you're okay to proceed in your environment. If anyone has any idea why some files fail to mount I'd like to hear. That's the reason I am sharing this now 🙂

Edit: Just as follow up... if anyone wants to quickly see if they'll have Mount-DiskImage issues then you can use the below.

$tests = Get-ChildItem "X:\Path" -File -Filter UVHD-S*.vhdx | Sort Name

New-Item -Path "X:\Path" -ItemType File -Name 'aaaa.txt'

ForEach ($test in $tests){
Write-Host "This is "$test.FullName -ForegroundColor Green
Mount-DiskImage -ImagePath $test.FullName -ErrorAction SilentlyContinue -ErrorVariable MountError | Out-Null;
If ($MountError){
Write-Host "Failed to mount" $test.FullName -ForegroundColor Yellow
Add-Content -Path "X:\Path\aaaa.txt" -Value $test.FullName
}
Dismount-DiskImage -ImagePath $test.FullName | Out-Null
}

We are looking for this script as well! Would you share it when it's available? 

Hi. Would also like to see a MS UPD to FSLogix container script or process please.
